Scupper-pipe leaking:

If you get a bad leak in the scupper pipe, and cannot get at it from the inside, the following method is a quick and sure way of stopping the inflow of water: Cut a round disk of wood about five times bigger across than the outside opening of the pipe. Bore a hole in the middle of this disk just small enough to pass a strong cord through and knot. Then on inside of the disk fasten a good big wad of cotton batting, or oakum; this you can do with tacks, thread or glue. I have used thick paint and cotton wadding pulled out of an old quilt. When the disk is ready, take another line and weight it with a sinker, drop it down the scupper pipe until it hangs outside, then fish it up with a boat hook and bring the end on board. Marry the end of this cord to the cord attached to the disk. Then haul the cord in through the pipe until the disk comes up against and closes the scupper hole. By taking a stick and making a windlass of it you can roll the cord up tightly and secure the disk so it will not slip.
